This invention relates to mp rovements in racliator caps, or apparatusoarecl thereb The prmary object t-hs nventon s the provson of an mprovedemblem or devee adaptecl to be part of a racliator cap for pos1- ti0ningover the top water nlet openngs of automobile ra'diators, ancl whch hasinuprovecl means thereon to permt the efficent cleterminaton of thethermal eflicency of the water wthnthe radiator.

A further object of ths iuvention s the provsion of an mproved raclatorcap, whch includes an ornanent or emblem whch may be characcerstio ofthe emblema adoptel by the manufacturer of the car upon whch the cap sto be used; the emblem havugeharacterst-c means thereon whchmaybe comm0n to any number of d1flerent emblems, to

display the slogan or name of the car or manufacturer 01' the car at thefront thereof; che improvecl cap havng means assooiatecl in a novelrelation therewth to illuminate a compartment wheren the rays of lghtthrow the slogan or nameinto relef; the improvecl dev-ice havng athermometer assooiafied therewth in aneficient and llumiriated relatoi1or.determnng th e temperature ofthe water in the -rac liator i1pon whchthe cap is positioned. 7 Other objects and aclvantages of ths 111-vention Will be apparent-cluring che oourse of the ollowng cletaleddescrption.

In the accompanyng clmwing, orm1ng a, pat of th s specifictin, andwherensimilar reference oharacters designate corresponclmg pats throughout theseveral vews,

Figure 1 is a, front el-evaton of the 1111- proved clevce aclaptel to bedetachably connek:ted upon a radiator cap, 01 rigclly attachecl as apart of the cap.

Figure 2 is a rear View of the clevce of Figure 1, showng parte inseot-on.

Figure, 3 is a cross sectional view taken through the mproved radatorcap structure, substantally on che lime 8-8 of Figure 1.

In the dretwng, wheren for the pur'pose of ilhistraton s shoWn Onlyapreferred embdiment of the nvention, the letter A may geuerallydesignate che part of che radiator u1ay be slpped through a sutableopening cap in whch ths nventon lies, whchmay include a base 10 having abott0m plane surface 11. Centrally from the base 10 clepends a hollowscrew threaclecl ,sha,nk 12 whioh m an ordinmycap base (not shown); nutmeaus 141 beng 'acljustable tbereon to c1amp beneath the top Wall oi thecap toattach the apparatus A upon the cap base, in a manner Whoh s welluuclerstood. i

In the preferred arrangement the base 10 may have ntegrally castorotherwse connectecl therewth-spaced wings 17 and 18, which arcuateupwarclly in spaeed relaton end tl1en inwarclly ai; their apces 19,toprovide a sori: ofopenng or area 20 wherenit s clesrecl to oonneetcertain parte ofthe inveuton to be more fully described. The wngs 17 and18 are formed as a, body wheh bus a, comPartment 21 theren mmecliatelyabove the base 19; the eompartment- 21 extenclng upwardly along the wngs17 and 18. This oompartment is open at the rear of the Wings, end adetachable cover plate 22, Shapecl to conform wth che outline of thewugs 17 ancl 18, above che base 10, s provdecl, end adaptedto bedetachably conneced to che margiusof thewngsl7 and 18 by Screws2l, toclose the cor1partment 21.

In axial algn'ment With the shztnk'l2, the se fcasting s pro.vdecbwth Vasort offrustocoriical sha'nk 25, -extehclug upwafdly into the spacebetween the Wn'gs 17 and 18, and up0n which is.ntegrally ofotherwsleconnected laterallyfextendng urns 27 and 28, whieh .respectively extendtowmrds the wings ,17 'aud 18, and may be coriueeted therewith, fclesre'dQ A compartment 30 s providecl in che upper part of the shank25, Whch extencls into thearncis27 ancl 28, butwhch s seprzxted from thecompartment 21 except by me2ins of ani openng tl1ro-ugh Which athemometer stem 31 extends; ths stem 31beng st1itably conneoteclon thebase 10, aricl at its lo'wer end extenclng into the hollow screwthrecled shank 12, and thenc upWzirolly through the eompaftment 21 andvertcally 'nto the o;ompartmenii 30, as shown in Figure 2, terminatngshort of the top wall 35 above the compartment 30. This thermoneter stemreceive e1ectric Iight bulbs 60, by means ofa margnal strip 0f metal 4l,which s held,

in place by screws 42. This plate 40may be clamped against a flexiblegasket if desred.

A Verteal strip 44 of the glass plate- 40 is transparent, mmedately, t 0themear of: the upper end of the the'rmometer stem 31, thru Whiehthethermometer stem s y-isible from thedriyers -seat ofthe velcle, 130determhe thetemperatu're of;the water in the radiator uponwhiehfihecap-s positioned. Otherwse the-rear sur-aeeof t'he plate 40 s opaque at 44The front Wa1l of this 'casiug, shown at 4'jin Fg'ures 1 and 3 ofthedrawing, may be sr1itably pr0Vdedwthstencil-lke openngs 48,intheferrriofltters or other, indeia pertnent to the car or otherarticle or 1riatter Whch the capis-adapted 150 represent or advertise;Inthi's front wa1l 47 is also provided a-n openng50 between-the arms 27and 28; mnedately 'at the front of the upper por'tion ofthethermor'n'eter stem 31, as a means of admttng aelejar vsion of thetremometer-stem, duringdaylight travel, and to aford a viewf Ofth'ethermometer stem from the front of thevehcle. V

Theend wa11s 55 and56 of the arms27 and 28are provided with sockets 58adapted to wh'ch no-illuminate the cdmpartment 30 ai; both sdes ofthethermometerstem 31, so that itmay be readly vsible thru che openings 44and 50. The wires 6lfrom the bulb sockets 58:ex tendjtransversely thruopenings in the casngwalls of the emblem wings 1and 18, and extenddownwardly through the come partment-2l, passng through an opening 68 mthe base 10, leadng to any sutable location, prefe*ably and insertngplug 65, as shownin Figure 2. e

It s apparent -fromfl1e foregoing that a novelradiator cap has beenprovded, emb odying important structural features whch Will permt thecap to dsplay an emblem or other insignia in such manner thatanilluminfaed eompartment may display advertising or otherydata to the front of the veh'cle, and and illuminate a Water temperature indicator sothat the. driver of the vehcle may readly observe the same.

Varous changes in the shape,sze, and arrangement O'f parts may be madeto the form, of invention heren shown anc1 described, without departngfromthe spirit of the invention or the scope of the claims.
